AUTOGRABQHIC REGISTER.

Application filed November 16, 1922. Serial No. 601,204.

' New York city, in the county of Bronx and State of New York, have invented certain new and useful Improvements in Autographic Registers, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to autographic registers and the like and in certain of its aspects particularly relates to registers of the pin-wheel type.

It is my object to provide a machine which will furnish the positive aligning characteristics of a pin Wheel feed and the advantages of the ejecting bypin wheels with the advantages of a pull-out type of autographic register. I

It is a further object to provide in such a combination a register in which the advance may be mad v step by step to disclose additional writing spaces, and still maintain constantly the alignment of the several sheets of paperin forward and lateral directions.

It is a further object to provide an unwinding means for the sheets of paper which will not impart the strain on the paper at the point of its contact with the pins of the pin wheels which is now characteristic of pin wheel machines when the paper is both unwound and ejected at the same time-by the same agency.

A feature of this invention is the provision of a pin-wheel type of register in which the feeding of the webs passing through the machine is'ell'ectcd by a simple push or pull movement of an operating part, or both, as distinguished from a solely rotary movement thereof. Ordinarily, registers of .the pin-wheel type are operated by the rotation of a crank; but, according to this invention, the feeding is effected by, or is a consequence of a longitudinal movement v of the pin-wheels. In some embodiments of this invention the longitudinal movement of the pin-wheel is accompanied by a rotating feeding movement, while in other cases the webs are fed by the pins of the wheels without rotation of th latter.

A further feature of this invention is the provision of means and the arrangement of parts whereby the webs are fed from their supply rolls at such times as the pin-wheels are not rotating, and irrespective of the rotation of the pin-wheels. This has the effect of enabling the webs to move over the pinwh-eels without liability of tearing and of permitting the parts to be made less accurately, thus reducing costs of production.

Another feature of this invention is the provision of a register which, without decreasing the hand-rest space and without necessitating the use of short forms, mayv be made substantially shorter than-ordinary registers having the same capacity for sup ply rolls of paper. This is accomplished, in some forms of the invention, by the provision of a writing'opening or zone which is preferably about one-half the length of the form, and by providing for the feeding of the normally concealed half of the form tothe writing zone by a simple .operation. The necessity of feeding the webs during the writing or filling-out ofa form is not objectionable because as a general rule most of the forms are only half filled by items, the surplus being provided.

merely for the purpose of enabling unusually larg numbers of items to be written.

- In this form of the invention, the entire second half of the form may be fed or moved to the writing zone by a single operation or by means of auxiliary mechanism for feeding the webs a line at a time. This line space mechanism may operate independently of the pin-wheel or other feeding mechanism.

As above stated the feeding of the Webs, according to the present invention, is incidental to a traveling movement of the pin- 1 wheels. For this purpose, the pin-wheels are mounted on a carriag to move to and fro on the main frame of the register. In some forms of this invention, this carriage also embraces the platen for supporting the webs during the writing operation. In other forms, however, the platen is independently supported.

Other features and advantages will hereafter appear.

In the accompanying drawings:

- Figure 8 is a side view of another form ofthis invention.

Figure 9 is a front view showing part of the feeding mechanism of the register shown in Fig. 8.

In the form of the invention shown in I Figs. 1 to 7 inclusive, the frame of the maother structural features of the chine comprises side plates 20 and a por- .tion or hand rest 21 at the top formed inprinted or ruled, ultimately pass under the hand rest 21 and over the platen 27, and while upon the platen are in position for use in the. writing opening orzone 28 im mediately in front of the hand rest 21. The

webs are held in writing position by pins 29 of pin-whecl30 which are mounted upon and are secured to a shaft 31 so as to re tate in unison. The pins 29 engage perforations 32 in the side margins of the webs 'and thus positively control the 'webs and cause the several superposed webs to feed in accurate unison without danger of them creeping relatively.

According to this invention, the feeding of the webs is accompanied by a longitudinal movement or travel of thepin-wheels. In this traveling movement of the pinwheels, they may or may not, according to articular embodiment, be accompanied by t e platen.

In the embodiment of the invention shown in Figs. 1 to 7, in which only one-half of the form is exposed at the writing zone at one time, the platen 27 ismounted to travelwith the pin-wheels 30, and, for this purpose, the pin-wheel shaft 31 is mounted to rotate in a frame 33 comprising downwardly extending sides 34 and a top portion 35 formed integral with the platen 27. At the rear of the platen 27 is provided with downwardly extending arms 32 carrying rollers 36 riding on rails 37 struck-up from the side plates 20 of the frame, and it is by means of these rollers 36 and the rails 37 that the rear of the platen issupported for traveling movement. The forward part of the platen and the pinwheel frame 33 is supported at each side by means of a inion mounted-on a stub shaft 39 earned by the sides 34 and which ride upon a rack 40 secured to the side plates 20 of the frame. The racks 40 and the pinions 38 have other functions which will hereinafter be described, and, so far as the supporting of the forward part of the platen is concerned could be replaced by simple rollers and rails.

As shown in the drawings, in this form of the inventionthere is only one-half of the form exposed in the writing zone at one time, and this has the advantage that the forms may be written upon at all places without the operators hapd resting thereon, thus preventing smudging of the carbon copies of the form. It also has the ad vantage of permitting the use of carbon sheet 41 which are only half the width of the usual carbon sheet for the same length form. Because of this arrangement, it is ensured that the carbon sheet is fully used. Ordinarily, since only about one-half of a form is used, only one-half of the carbon sheet is used, and consequently the unused part of the carbon sheet must be discarded with the used, resulting in considerable loss. The present invention as above set forth overcomes this disadvantage. The carbon sheets 41- are supported in a frame 42 at the side of the machine in the usual manner.

\Vhen the parts are in position shown in Figs. 1 and 2 and the first half of the form has been written upon, and itis desired to move theentire other part to writing position, the platen 27, which carried the pin-wheels 30, is pushed forwardly by means of a handle 43 at its end and this causes the portion of the platen 27 and webs 26 carried thereby which was previously located beneath the hand rest 21, to be moved into the writing zone. This advance of the webs to the writing zone is. not attended by arotation of the pin-wheels 30 but these are held against their tendency toward retrograde rotation by. a spring urge back-check pawl 44 pivotally carried by a bracket 45 mounted on the pin-wheel frame 33 and engaging a ratchet wheel 46 secured to the pin-wheel shaft 31, the pins 29 merely acting to hold the webs on the platen to move therewith.

At this point it should be noted that the pins of each pin-wheel pass through a slot 47 provided in the top 35 of the pin-wheel frame 33 the forward portions of which act to strip the webs from the pins 29 as they are moved across the slots by the pins. The

webs are held in engagement with the pins 29 by slotted blocks 48 having depending portions 49 secured to the side plates 34- of the pin-wheel frame. The pins passing through said slots while the webs are held to the top plate 35 by the parts of the blocks been written upon it is desired to deliver the form past the knife bar 51 so that it can be severed from the next form and V used. According to this invention, in the form now being described, this is accomplished by a. simple backward movement returning the platen to its normal position.

Of course,-if the second half of the form was not needed, then the first step in the operation of delivering the form is to push the handle 43 forwardly and the latter is then immediately returned to normal position by apulling action. During the return movement of the parts, a full form length is fed past the pin-wheels and this is accomplished by means. of the pinions 38 which mesh with the-racks 40 and also mesh with pinions 52 mounted on the pin-wheel shaft 31 to rotate the latter ina forward direction only, by means of a'one-way clutch 53. The ratio of the gearing 40, 38, 52 is such that for the rearward travel of the pinion 38 over a distance equal to the length of onehalf a form the peripheral distance traveled by the. pin-wheels with relation to the platen will equal one form len th.

It should be understood that th1 s advancement of the webs refers merely to the delivery of the webs past the knife bar 51 and not the feeding of the webs from the rolls 24, for, according to this invention, the webs are fed from the rolls independently, that is, without. any of the work being done by the rotation of the pin-wheels. This is accomplished by feeding one form length from the rolls when the platen and pinwheels are moved forwardly. One-half of a iorm length is fed by the actual forward mo ement of the platen and pin-wheels, sin e the webs pass over rollers 54 at the rear of the frame 20. The other half form length is fed at the same time by means of a bail 55 supportingmollers 56 engaging the webs between the stationary rollers 54 and other stationary rollers 57 located beneath the rollers 54, the webs passing from their rolls 24 over the rollers 57 then over the rollers 56 and finally over the rollers 54 to the platen 27. When the platen is moved forwardly, the bail 55 is also moved'for- Wardly to feed one-half form length from the rolls 24 by its movement; and, its movement is effected'by means of a slotted link 58 pivotally carried at 59 by the platen frame arms 35 and engaging a pin 60 secured to the bail 55. During the forward movement of the platen, the end of the slot in the link 58 engages the pin 60 and draws the bail forwardlya The movements of the bail are limited by a pair of pins 61 adjustably mounted in the side plates 20. \Vhen vthe platen is returned, the slack in the free stretch of the Webs is taken up by the rotation of the pin-wheels and return of the bail 55 is positively effected by the link 58 in the same manner as it is moved forwardly. It will thus be seen, that during the delivery of the Webs there is no drag produced there-. on by the rolls 24 and that the only work which the pin-Wheels need do is to either hold the webs during feeding-off of the webs from the rolls orto advance the fed-off webs over the platen during the delivery of the forms after the writing has been finished.

In case there is only a few lines to be written upon, or in case the operator prefers to advance the form line-by-line during the writing of the second half of the form, the platen may be advanced by line spade mechanism provided for\ the purpose. In the form shown in Fig. 1, this line space mechanism comprises a single element consisting of a handle 62 located outside of the side plate 20 and an arm 63 located inside the plate 20 and secured to the handle by means of a rod 64 passing through a slot 65 in the side plate. The upper portion of the arm 63 is provided with a projection 66 adapted to enga e-ratchet teeth 67 carried by the platen 2 The arm 63 is held with its projection 66 beneath the plane of the bottoms of the teeth 67 by means of a spring 68 which also tends to return the arm and handle to normal position after having been operated. In operation, when the handle is pushed forwardly theprojection 66 engages one of the ratchet teeth and advances the platen one line space at which time the movellti leo

ment'of thearm 63 is limited by engagement with astop 69. In returning it is necessary for the projection 66 to passone of the. teeth 67 and to permit this the slot 65 is elongated so as to allow a bodily descending movement of the handle and arm. This descending movement is opposed by a sprin 70 which tends to hold the parts elevated and which assists the spring 68 in returning and holding the'parts in normal position.

In Fig. 4 there is shown a modification of this line-space mechanism. In this form the handle and arm are not mounted for bodily ascending and descending movement. Instead, the arm 63 is provided with a pivoted pawl 66 adapted to be urged by a spring 68 into engagement with the ratchet teeth 67. In normal position, however, the pawl is maintained out of ran e of the teeth 67 by means of an abutment 11 engaging a cam surface 72 on the pawl. is operated, (that is, is moved forwardly), the cam surface 72 moves away from the abutment 71 and thespring 68 moves the pawl into engagement with the teeth 67. The continued movement of the handle and pawl advances the platen. During the return movements of the parts, the pawl merely passes idly over the ratchet teeth. The forward movement of the parts is limited by means of a stop 7 2 which is adjustable in a slot 73 for the purpose of permitting the movement of the platen to be varied to meet varying conditions.

As shown in Fig. 7, the top plate 21 is extended at 74 to overlie the portions of the webs which are perforated so that the writing zone exposes only .the portion of the form which is to be written upon.

The front plate 23, in the form ofthe invention above described, is left open directly in front of the path of the pinwheels so that the latter may move out wardly of the frame when the platen is moved to the position shown. in Figs. 6

and 7. v

The forward and rearward positions of the platen, and consequently the extent of feeding movement incidental thereto, are controlled by means of the stops 61 which are also used to limit the movement of the bail connected to the platen. The stops 6-1 are adapted to be adjusted in slots 5 in the side plate for the purpose of varying the extent of movement of the platen to accommodate forms of various lengths.

It should be understood that it also forms part of this invention to use the register above described with the normal writing positionof parts as shown in Figs. 6 and 7, especially in cases where the items written on the forms usually occupy more than one-half of the space of the forms. If this is done, the feeding op eration commences with a backward movement of the platen and is completed by a forward movement returning the garts to the position shown in Figs. 6 and 1 Another form of this invention is shown in Figs. 8 and 9 and in these figures the parts corresponding to the parts in ,Figs. 1 to 7 are noted by corresponding reference numerals to which have been added the prime .mark.

In this form of the inyention, the platen When the handle 27 is mounted to be stationary and consequently the pin-wheel frame 34 is independently mounted and has a rearwardly extending arm on which the rollers 36 are mounted.

The feeding of'the webs from the supply rolls is effected by the forward bodily movement of the pin-wheels which hold the latter at the front without rotating while at the rear. the webs pass over rollers 54. The movement of the pin-wheel frame to the forward limit of its motion is sufficient to feed from the rolls 24, as a consequence thereof, one full form length leaving nothing to ,be. fed-off; during the return stroke. When the pin-wheels are returned to normal position it is merely necessary for the pin-wheels to idly pass over the paper that has been fed and to feed this paper heneath the,severing knife 51. During the forward movement, the pin-wheels are held against retrograde movement by a backcheck pawl 44 and ratchet 46, while during the return movement the pin-Wheels are forced to rotate forwardly by means of a pinion 38 meshing with a rack 40, a gear 76 secured to the pinion 38', a gear 77 meshing with the gear 76, a sprocket 78 secured .to the gear 77, a sprocket 52' having a one-way clutch 53 connecting it to the pin-wheels, and a chain 79 connecting the sprockets 52' and 78. The pitch diameter of the pinion 38' is the same as the diameter of the pin-wheel proper and the ratio of the gearing is 1:1 so. that the rotation of the pin-wheels will just feed the paper fed-off the rolls past-the knife.

Immediately in front of the knife bar 51"there is provided an auxiliary table 80 to cover an opening at the top'of the register and to provide means for. receiving the leading edge of the form as it is being fed past the knife bar.

The front of the pin-wheel frame is supported on the pinions 38 which ride on the racks 40' and to hold thepinion 38' in mesh with the rack there is provided directly above it a roller 81 riding on the t-ra '37. The shaft 31 for the pin-wheels nd the shaft 39 for the pinions 38 extend across the machine and serve to tie together opposite sides of the pin-wheel frame.
